The partially-clothed, mutilated body of Corriann Cervantes was discovered in an abandoned Houston apartment on Saturday. The two boys allegedly hit her with a toilet tank lid, stabbed her in the face with a screwdriver and sexually assaulted her with a plastic rod from window blinds. She was also strangled.

An exact cause of death has not been determined.

Jose E. Reyes, 17, and an unnamed 16-year-old have been charged with murder.

One friend told the Chronicle the three were friends at school, but Cervantes had stopped hanging out with the boys when they started using pot.

Assistant Harris County district attorney John Jordan said it was the 16-year-old who wanted to sell his soul.
